Ok so version 3 2002. I am not sure of that carrier ID. If it is Orange you should be OK. If you hard reset and lose any one of the above mentioned you can find the software. Anyway with 2002 you can get the latest Photo Album free at http://www.gaborvision.com.tw/support/driver.htm
Pickup the CM35D drivers and install.
MMS - the 2002 version is available as a separate program. It was on the Orange original CD if you had one. No problem getting it though.
File Manager, If you loose it get Smart Explorer, there is a freeware version and it is better than the stock explorer.
So you should have no problem resettting and see what happens.
